Nanotechnology promotes the full-thickness diabetic wound healing effect of recombinant human epidermal growth factor in diabetic rats

We utilized a modified double-emulsion method with poly(lactic-co-glycolic acid) as the carrier to prepare recombinant human epidermal growth factor (rhEGF) nanoparticles. The morphology of the nanoparticles was detected by a transmission electron microscope. The particle size distribution was measured by a laser analyzer with a zeta potential meter. Enzyme-linked immunosorbent assays were performed to determine the rhEGF encapsulation...
